14.2 Changing the fuse
It is mandatory to use fuses only with the indicated characteristics
The use of undersized fuses can cause the interruption of power to the device during normal working
conditions. In this case there is no risk to the user, nor for the patient, but the device turns off at
inopportune moments, and this can cause data loss
The use of oversized fuses can lead to damage to the internal electronics of the device due to current
overload for non-interruption by fuses. In this case you do not identify risks to the patient, but on the user
or damage to the device and then stop working and possible data loss.
The procedure to change the fuse is very similar to changing the voltage, except that in Step 3 you also need
to remove the blown fuse from its seat and replace it with an identical one as indicated in the following table
and on the instrument label:
Power supply voltage
Fuse type
Fuse value
220 240 V
20 x 5 mm
2.5 A 250 V antisurge
After replacing the fuse, continue with step 5, of course without turning the fuse box, and step 6 and check
that the desired voltage is indicated.
